If deserts are dry, lifeless places… why do they contain so much oil? It seems strange. Some of the world’s richest oil reserves are found in places like the Middle East, surrounded by endless sand. Regions like the Arabian Desert or the vast Sahara Desert produce enormous amounts of petroleum. But here’s the twist. Millions of years ago… these deserts weren’t deserts at all. They were oceans.
